RALEIGH, N.C. -- The executive director of the North Carolina Democratic Party has resigned amid concern among party activists about high turnover at the party headquarters and harassment allegations there.

Jay Parmley, who became the top administrator last year after holding a similar post in South Carolina, resigned Sunday.

He wrote in a resignation letter that he had "never harassed any employee at any time at the (state party) or in any other job."

State party leaders raised concerns after e-mails circulated last week that mentioned the allegations, which the party has not detailed.

State party chairman David Parker agreed that the issues involving Parmley were becoming a political distraction, particularly in an election year.

The Democratic National Convention will be held in Charlotte in less than five months.
